A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The cell membrane regulates the flow of substances into and out of the cell.
The cell membrane, commonly referred to as the plasma membrane, serves as the body of a cell. It also keeps the environment inside the cell constant, and that membrane has many functions. One is to introduce nutrients into the cell while removing toxic chemicals from it. Another is that the cell's plasma membrane, which is its outer membrane, will have proteins that interact with other cells. These proteins may be glycoproteins, which also contain a sugar moiety, or lipid proteins, which contain both a protein and a fatty acid. Proteins that stick outside of the plasma membrane also allow for cell-to-cell communication. The cell membrane also provides some structural support.

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
1. oxygen
2. co2
3. co2
4. oxygen
producers: photosynthetic plants
consumers: humans or any life that breathes oxygen
How are each of the spheres connected to the carbon cycle?
biosphere: regions occupied by living organisms need the carbon cycle to survive.
geosphere: is the habitat of the biosphere, w/o the geosphere plants would not be able to perform carbon fixation.
atmosphere: carbon cycle can contribute to global warming.
anthrosphere: involves the external environment and plants, so the carbon cycle is present.
hydrosphere: carbon cycle still happens in submerged plants as sunlight can pass through water.
How is the growing human population going to affect the carbon cycle?
more humans means more carbon being produced. more co2, more cars, more pollution being expelled into the air. Some things that can occur with the carbon cycle include an excess of co2 being present in the air as there isn't enough plants to efficiently remove it from the air, which can lead to co2 buildup in the atmosphere resulting in climate change.
